WILLIAM LAVVRENOE FREESE, OF MOHAWVK VILLAGE, OHIO.

R-OAD-SCRAPERI.

SPECIFICATION forming part: of Letters Patent No. 306,913, dated October 21, 1884-.

Application filed May 3, 1584.

(A 0 model.)

To aZZ whom it may concern.-

adjusting-rod pass, and nuts are employed Be it known that I, W'ILLIAM L. FREESE. a 1 to adjust the teeth by adjusting the horizoncitizen of the United States, residing at Mohawk Village, in the county of Ooshocton and State of Ohio. have invented a new and useful Road-Scraper, of which the following is a specification, reference being had to the ac companying drawings.

This invention has relation to road scrapers designed for use where there is sod or grass, roots, sticks, mud, or rubbish of any kind that is difficult to get into a scraper of the ordinary kind; and it consists in the construction and novel'arrangement of parts, as will be hereinafter fully described, and particularly pointed out in the claims.

Figure 1 is a view in perspective of a roadscraper embodying my improvements. Fig. 2 is a detail view of one of scraper-teeth removed, and Fig. 3 is a detail view of the threepart adjusting-rod.

Referring by letter to the accompanying drawings, a a designate the end boards of the scraper. which are curved. as shown,- and en larged at their rear ends, and connected by the cross-rail b, w ich forms the rear wall of the scraper. The handles are of the ordinary construction. The cross-rail b is mortised to receive the tenons c on the rear ends of the teeth (Z, and nuts and washers are employed to secure them in place. These teeth dare carved in their upper edges from heel to point, and they are also curved in theirlower edges from the heel to a perforated shoulder, e, from which latter they are beveled to the point. The ends of the cross rail 1) are journaled in the end boards, so that the pitch of the teeth may be changed with relation to said end boards. The horizontal portion f of the adj usting-rod is passed through the perforations in the shoulders e of the teeth, and is provided at each end with a hole, 9, through which the lower ends of the threaded'portions h h of the tat rodf up and down upon the Vertical rods h h, the upper ends of which are secured to the bail k of the scraper, so that the teeth may be made to stand perpendicular or slanting forward. The eyes at the ends of the bail lc connect with tixed pins a in the end boards, a, to effect this adjustment. If a tooth be broken, it may be easily taken out by removing the rodf and a new one put in its place.

This scraper is simple and cheap and is thoroughly efficient for the purposes for which it is intended.

Having thus fully described my invention,

what I claim as new, and desire to secure by Letters Patent ofthc United States, is-

1. In a rOadscraper, the combination, with the end boards jonrnaled on the ends of the niortised cross rail, of the removable teeth, the three-partv adjusting-rod, and the bail, substantially as sp. ciiied.

- 2. in a road-scraper, the combination. with the end hoards and mortised rear wall, of the removable teeth, and mechanism. substanaally as described, for adjusting them vertic 11 y, substantially as specified.

3. In a road-scraper, the combination of the end b 'ards journaled on the ends of the inortised rear wall, the perforated and tenoned removable teeth, the horizontal rodf, having holes in its ends, the vertical-threaded rods h h, passing through said holes and secured in place by nuts, and the bail connected to the upper ends of the rods lL/l, substantially as specified.

in testimony that I claim the foregoing as my own I have hereo atlixed my signature in presence of two witnesses.

WILLIAM LAWRENCE FREESE.
